Acreichthys tomentosus
This little weirdo is one of my favorites because it's got that goofy filefish "face," a knack for wedging itself into rockwork, and a ton of personality once it settles in. People love them for the chance they'll snack on nuisance Aiptasia, but even when they're not on pest patrol they're just fun to watch cruise around and pick at stuff all day.
Ambassis urotaenia
This is one of those see-through glassy perchlets where you can literally watch the organs shimmer when it turns-super cool in the right lighting. In the wild it hangs around river mouths and mangroves and cruises in groups, so it does best when you keep a little gang of them and give them some open swimming room.
Ambastaia sidthimunki
This is the little "Sid" loach people fall in love with once they see a whole group doing their goofy zoomies and clicking at each other. They stay tiny but act like big loaches - always busy, always social, and way more confident when you keep them in a proper gang. Give them sand, hiding spots, and lots of buddies and they really shine.
Amblyeleotris randalli
Randall's shrimp goby is that little candy-cane striped goby you'll see parked at the entrance of a burrow, doing sentry duty like it's getting paid for it. The really fun part is the partnership with a pistol shrimp-goby keeps watch, shrimp does the digging, and they basically run a tiny construction site in your sand bed. Give it a cozy sand area and a few rubble bits and it'll settle in and start acting like it owns the place (in the cutest way).
Amblyeleotris wheeleri
Amblyeleotris wheeleri is that classic shrimp-goby that picks a sandy spot, makes a burrow, and basically turns your tank into a little nature documentary if you pair it with a pistol shrimp. It hangs at the burrow entrance, does the whole lookout routine, and flashes those red bands and blue speckling when it is settled in.
Amphiprion ocellaris
Ocellaris clowns are that classic orange clownfish look-three white bars, a little black edging, and a ton of attitude packed into a small fish. They'll "pick a spot" in the tank (often a corner or a coral) and do that cute hover-wiggle thing, and a bonded pair will usually settle in fast and act like they own the place.
Ancistrus cirrhosus
Ancistrus cf. cirrhosus is a small Loricariid catfish known for its sucker mouth, armored body plates, and the distinctive facial bristles (especially prominent in adult males). It is primarily nocturnal and spends much of its time grazing on biofilm and algae from surfaces, making it a popular, hardy "algae-eater" in community aquariums.
Betta albimarginata
This is one of those wild bettas that feels more like a tiny aquarium predator than a "fancy fin" betta-sleek, quick, and always watching what's going on. The males are awesome with that crisp white edging on the fins, and the coolest part is the dad carries the eggs in his mouth, so you'll sometimes see him just chilling and not eating for a bit while he incubates.
Betta macrostoma
This is the famous "Brunei beauty" wild betta - a chunky, orange-red fish with an awesome little eyespot on the dorsal fin and a big attitude-free personality (until you put two males together). The really cool part is breeding: the male is a paternal mouthbrooder, and the pair does that weird "kiss" egg transfer behavior people geek out over.
Betta splendens
Betta fish, also known as Siamese fighting fish, are popular for their striking colors and flowing fins. They are known for their territorial nature, especially males, which can display aggressive behavior towards each other.
Brachygobius doriae
Brachygobius doriae is one of the classic "bumblebee gobies" - tiny, bottom-hugging little characters that perch on rocks and sand and stare at you like they own the place. They're at their best in a calm setup with lots of caves and leaf litter, and they really shine once you get them eating frozen/live foods reliably (they're slow, picky eaters). Also: they're one of the species that gets mislabeled a lot in shops, so it's super common to see them sold under the wrong bumblebee-goby name.
Brachygobius xanthozonus
This is that tiny little goby with the bold black-and-yellow bands that likes to perch on the bottom and stare back at you like it owns the place. It's happiest in lightly brackish water with lots of little caves and sight-breaks, and it's one of those fish that often refuses flakes-frozen/live meaty foods usually flip the "yes, I will eat" switch.
